Can anyone compare performance of the new X-5 to the older X70? I have an X70 that had to be sent off for repair. (I thought they cwould call and say it couldn't be repaired, but it has been a month...). I was said to see they had discontinued the x70 and x90, but then saw the X-5 appear. Would it be a good replacement?

The lens on X-5 goes quite a bit wider (22,3mm vs 26mm equivalent). Most improved was video capturing: while X70 had only 720p @15fps the new X-5 has 1080p @30fps and also 720p @30-60fps. Shutter lag was an issue at X70, while X-5 has better/faster AF and overall speed. Among other things battery life is better on X-5.
